原型观测在水工建筑物特别是坝工建设中的作用已为越来越多的人所认识。几乎每一篇写到原型观测的文章或以此为题目所作的发言中,都会提到原型观测的目的是为“施工和运行提供安全监测,为设计的改进和提高积累资料”。但在我国目前的状况下这两个目的难于达到。原型观测仪器的埋设、保护和正常运行难,即便有一些原型观测资料但要整理成文用以指导 The role of prototype observation in hydraulic structures, especially dam construction has become more and more recognized by people. Almost every article written or written on the subject of prototype observation mentions that the purpose of prototype observation is to provide “safety monitoring of construction and operation, and accumulation of information for the improvement and enhancement of design.” However, these two purposes are difficult to achieve under the current conditions in our country. Prototype observation equipment embedding, protection and normal operation difficult, even though there are some prototype observations but to be documented to guide
